Summaries for Ablepharon-Macrostomia Syndrome

NIH Rare Diseases : 53 Ablepharon macrostomia syndrome is genetic disorder characterized by absent eyelids (ablepharon) and very large mouth (macrostomia). Other common signs and symptoms include abnormal external ears, fusion (syndactyly) of the hands and feet, skin findings (such as dry and coarse skin or redundant folds of skin), absent or sparse hair, genital malformations, and developmental delay. Other reported findings include underdeveloped cheeks (malar hypoplasia), absent or very small (hypoplastic) nipples, umbilical abnormalities and growth retardation. It belongs to a group of diseases called ectodermal dysplasias (genetic disorders that involve defects in the skin, hair, nails, sweat glands, and/or teeth). Ablepharon macrostomia syndrome is caused by mutations in the TWIST2 gene. Inheritance is autosomal dominant, but most cases are sporadic (when there are no other cases in the family). Treatment is aimed toward correcting the problems that are present. Mutations in TWIST2 gene also cause the Barber Say syndrome and Setleis syndrome, other ectodermal dysplasia syndromes which have very similar features.  

MalaCards based summary : Ablepharon-Macrostomia Syndrome, also known as ablepharon macrostomia syndrome, is related to walker-warburg syndrome and barber-say syndrome, and has symptoms including dry skin and eye manifestations. An important gene associated with Ablepharon-Macrostomia Syndrome is TWIST2 (Twist Family BHLH Transcription Factor 2), and among its related pathways/superpathways are O-linked glycosylation and Cardiac Progenitor Differentiation. Affiliated tissues include skin, eye and lung, and related phenotypes are hearing impairment and global developmental delay

Disease Ontology : 12 A syndrome characterized by ablepharon, macrostomia, abnormal external ears, syndactyly of the hands and feet, dry and coarse skin or redundant folds of skin, absent or sparse hair, genital malformations and developmental delay and that has material basis in heterozygous mutation in the TWIST2 gene on chromosome 2q37.

OMIM : 57 Ablepharon-macrostomia syndrome is a congenital ectodermal dysplasia characterized by absent eyelids, macrostomia, microtia, redundant skin, sparse hair, dysmorphic nose and ears, variable abnormalities of the nipples, genitalia, fingers, and hands, largely normal intellectual and motor development, and poor growth (summary by Marchegiani et al., 2015). (200110)

UniProtKB/Swiss-Prot : 75 Ablepharon-macrostomia syndrome: A congenital ectodermal dysplasia characterized by absent eyelids, macrostomia, microtia, redundant skin, sparse hair, dysmorphic nose and ears, variable abnormalities of the nipples, genitalia, fingers, and hands, largely normal intellectual and motor development, and poor growth.
